Question 1

Is MOA-5/AEO-5 harmful to humans? Does it have an impact on the environment?

Accepted Answer

MOA-5/AEO-5 causes skin and eye irritation in humans, but under normal industrial use, the risk is controllable; for the environment, it is a biodegradable nonionic surctant with low ecotoxicity. Detailed Explanation MOA-5 (AEO-5), as a C12-14 tty alcohol polyoxyethylene (5) ether nonionic surctant, poses the primary hazard to humans through skin irritation and severe eye irritation. According to the Globally Harmonized System of Classification and Labelling of Chemicals (GHS), this product is classified as skin irritant (Category 2) and serious eye damage/eye irritant (Category 2A), with hazard codes H315 (causes skin irritation) and H319 (causes serious eye irritation). It should be noted that this product is not highly toxic or carcinogenic; its hazards are primarily due to local irritation from direct contact, rather than systemic toxicity. Skin contact may result in redness, itching, or dry degreasing, while eye contact can cause pain, tearing, and conjunctival congestion. However, the product has low volatility, so inhalation risk is low under normal ventilation conditions. As long as protective gloves, goggles, and clothing are worn according to safety regulations, operational risks can be effectively controlled. If skin is contaminated, immediate washing with plenty of soap and water can reduce irritation. In terms of the environment, MOA-5, as a tty alcohol polyoxyethylene ether surctant, has good biodegradability and can be gradually broken down by microorganisms in natural water bodies, with low potential for long-term accumulation. Its acute toxicity to aquatic organisms is low to moderate, but it is still recommended not to discharge large quantities of untreated product directly into water bodies to avoid short-term impacts on aquatic ecosystems. Overall, under reasonable use and proper disposal, the environmental impact of MOA-5 is limited and controllable.

Question 4

Does MOA-5AEO-5() meet environmental requirements? Can a test report be provided?

Accepted Answer

MOA-5/AEO-5 is a readily biodegradable nonionic surctant that meets general environmental requirements. Its content of heavy metals and other harmful impurities is extremely low, making it an environmentally friendly additive. Detailed Explanation MOA-5/AEO-5 (C12-14 tty alcohol polyoxyethylene (5) ether) is produced by addition polymerization of natural tty alcohols and ethylene oxide. Its linear alkyl structure endows the product with excellent biodegradability, allowing it to decompose rapidly in the natural environment after use without causing persistent organic pollution. According to data from the Guoli Chemical product database, the heavy metal content in this product is ≤10 mg/kg, and the arsenic content is ≤2 mg/kg, r below the hazardous substance limits for conventional industrial chemicals, posing a low risk to aquatic ecosystems. From a regulatory perspective, the AEO series (tty alcohol polyoxyethylene ether) is listed as an assessed and permitted traditional nonionic surctant under the EU REACH regulation, China's "Environmental Management of New Chemical Substances" and "Priority Control Chemicals List". It is neither a persistent organic pollutant (POP) nor a substance of very high concern (SVHC). This product is non-flammable (closed cup flash point >165°C) and is not classified as dangerous goods during transportation, thereby reducing the risk of environmental pollution from physical hazards. In terms of compliant use, this product only has skin irritation (H315) and eye irritation (H319) and does not carry severe environmental hazard labels such as acute aquatic toxicity or reproductive toxicity. However, it should be noted that although the product itself is biodegradable, as a concentrated surctant, it should be treated through a wastewater treatment system before discharge to avoid direct release into natural water bodies, which could cause local eutrophication. Technical Parameters (Environmental Indicators) Indicator ItemDataEnvironmental Significance Heavy Metal Content≤10 mg/kgr below ecotoxicological limits, safe for aquatic life Arsenic Content≤2 mg/kgMeets strict international limit standards Active Content≥99%High purity, low impurities, reduces unintended pollution Moisture Content≤1.0%Low moisture ensures product stability, reduces need for preservatives Free Alcohol Content≤2%Complete reaction, low residual monomer Flash Point (Closed Cup)>165°CNon-flammable liquid, reduces VOC emission risk BiodegradabilityReadily biodegradable (linear tty alcohol structure)Rapidly degrades in the environment, does not accumulate Regarding Test Reports Guoli Chemical currently does not provide directly downloadable third-party environmental test reports (such as SGS, CTI, or Pony testing reports) in its product database. However, as a compliant manucturer, routine outgoing products are accompanied by a Product Quality Certificate (COA), which includes measured data for key environmental indicators such as heavy metals, arsenic, and moisture. How to Obtain Official Test Reports:If you need the specific COA for a shipment batch, it can be included with the order, or you can contact the Guoli Chemical sales department to request it.

Question 8

How to use MOA-5 (AEO-5)? What is the recommended dosage?

Accepted Answer

The usage method of MOA-5 (AEO-5) varies by application field. The Guoli Chemical database does not include absolute fixed dosages for each field. The following recommended dosage ranges are based on the product's HLB value (10.5) and industry general experience. The actual optimal ratio should be verified through small-scale experiments. Detailed Description MOA-5 (AEO-5) is a nonionic surctant with the chemical name C12-14 tty alcohol polyoxyethylene (5) ether. This product is a colorless transparent liquid at temperatures above 25°C, and may appear as a white paste at low winter temperatures (≤25°C). If solidified before use, it can be appropriately heated to 25~30°C to restore fluidity for normal use. Since the product is easily soluble in oil and dispersible in water, when preparing water-based systems, it is recommended to pre-disperse it with a small amount of warm water or co-solvent before adding it to the main formulation and stirring evenly to achieve the best performance. The cloud point of MOA-5 is only 28~32°C (1% aqueous solution), meaning that when used in aqueous solutions, the operating temperature should not be too high; otherwise, "clouding" may occur, leading to reduced efficacy. If the formulation requires operation at higher temperatures, it is recommended to blend with other high cloud point nonionic surctants. Its critical micelle concentration (CMC) is 0.065 mmol/L, and the surce tension can be reduced to 28 mN/m, indicating excellent wetting and penetrating properties even at low concentrations. Recommended Dosage by Application Field The following dosage data are general references based on product characteristics and industry experience. The actual optimal dosage should be determined through formulation small-scale trials: Application Field Recommended Dosage (of total formulation weight) Usage Instructions Textile Printing and Dyeing Auxiliaries 2%~10% Used as a component of pretreatment scouring agents and leveling agents, can be compounded with other surctants, dissolved in warm water at 40~60°C before adding to the dye bath Leather Processing 1%~5% Directly added to the water bath in degreasing and soaking processes, works better when combined with alkaline auxiliaries Metal Cleaning Agents 3%~10% Compounded with alkaline auxiliaries and chelating agents, suitable for spray and immersion cleaning; recommended to keep operating temperature below the cloud point Hard Surce Cleaners 2%~8% Compounded with anionic surctants (e.g., LAS, AES) to enhance oil removal and wetting effects Household Detergents 2%~15% Used as primary or secondary surctant in laundry liquids or dishwashing liquids, providing excellent degreasing performance and moderate foam Pesticide Emulsification 5%~15% Used in combination with anionic emulsifiers (e.g., Agricultural Emulsifier 500#, 600# series) for preparing emulsifiable concentrates or water emulsions Coatings and Inks 0.5%~3% Used as a wetting and dispersing agent, added during the grinding stage to help disperse pigments evenly and improve storage stability Technical Parameters Parameter Value Ionic Type Nonionic Surctant HLB Value 10.5 Active Content ≥99% pH (1% Aqueous Solution) 5.0~7.0 Cloud Point (1% Aqueous Solution) 28~32°C CMC (25°C) 0.065 mmol/L Surce Tension (25°C, at CMC) 28 mN/m Density (25°C) 0.98±0.02 g/cm³ Appearance Colorless transparent liquid (>25°C) / White paste (≤25°C) Solubility Easily soluble in oil, dispersible in water Foaming Characteristics Moderate foaming Flash Point (Closed Cup) >165°C Application Recommendations 1. Optimal Compounding Strategy: MOA-5 has an HLB value of 10.5, which is in the medium HLB range. It can be compounded with anionic surctants (e.g., LAS, AES, SDS) or other nonionic surctants (e.g., TX-10, AEO-9). Compounding with anionic surctants can produce synergistic effects, improving detergency and salt tolerance. 2. Temperature Control: The cloud point of only 28~32°C is an important usage limitation for this product. In water-based formulations, when the operating temperature exceeds the cloud point, the surctant will precipitate from the aqueous phase, leading to a sharp decline in performance. If high-temperature operation is unavoidable, it is recommended to blend with high cloud point AEO-9 (cloud point about 60~65°C) or TX-10 (cloud point about 65°C). 3. Dissolving Tips: Because the product is easily soluble in oil but dispersible in water, when preparing water-based systems, you can first pre-disperse it with a small amount of co-solvents such as isopropanol or ethylene glycol butyl ether, or after adding it to the formulation, slowly raise the temperature above 25°C while stirring to ensure full dispersion. Precautions Safety Protection: This product is irritating to the skin (H315) and causes serious eye irritation (H319). Always wear protective gloves, goggles, and protective clothing during operation. Thoroughly clean the skin after operation. <strong

Question 10

What are the physicochemical technical parameters of MOA-5/AEO-5?

Accepted Answer

MOA-5/AEO-5 is a nonionic surctant with an HLB value of 10.5, and its physicochemical parameters cover multiple indicators such as appearance, solubility, surce activity, and general physical properties, with balanced overall performance. Detailed Description MOA-5/AEO-5, chemically known as C12-14 tty alcohol polyoxyethylene (5) ether (CAS No.: 68439-50-9), is a classic nonionic surctant. Its appearance changes with temperature: it appears as a colorless transparent liquid above 25°C, and turns into a white paste at or below 25°C. If users encounter low-temperature pasting before use, they can appropriately preheat it to restore fluidity without affecting product performance. In terms of surce activity, the critical micelle concentration (CMC) of this product is 0.065 mmol/L (25°C), and the corresponding surce tension can be reduced to 28 mN/m, demonstrating good intercial activity. The cloud point range is 28~32°C (1% aqueous solution), indicating that the phase behavior of its aqueous solution is sensitive to temperature, and attention should be paid to the impact of cloud point on usage effect in actual formulations. Meanwhile, the product has a water content ≤1.0%, an active content ≥99%, and free alcohol ≤2%, with high purity and few by-products, which is beneficial for formulation stability. This product exhibits excellent chemical stability in acidic and alkaline environments, is resistant to hard water, does not readily form precipitates with calcium and magnesium ions, and has good compatibility with anionic, cationic, and other nonionic surctants. It is a widely used general-purpose additive in industrial and daily chemical formulations.
